Hard Knocks, starring Rex Ryan and the 2010 New York Jets, doesn't premiere until August 11, but HBO is airing a twelve-minute preview tonight. When asked if there was anywhere cameras wouldn't be allowed, Ryan replied, "My shower will be off limits." The Jets otherwise have nothing to hide, he explained, adding that he's "definitely not the star" of the show. "I'm too boring," said the guy with the lucky pizza stain who once flipped off the crowd at an MMA fight. [USAT]
